MAGAZINE FOR SMALL-ARMS.

.; Application filed August 2,

Be it known that I, JnNs Lonny-photographer,-cit'izeniof Norway residingat Farsund, Norway, have invented certain new and useful: Improvementsin Magazines for Small-Arms, of :which the following is a specification.

The. present i invention relates to improvements magazines; for riflesand Y has for its object a magazine which is capableof carrying a agreater number of cartridges 'thanugun magazines. :Eormerly -known. Thepresent construction is especlally adapted for automatic 1 small-arms.

The capacity. for i holding great number of cartridges is obtained bygiving the magazineva escrow-shaped form, and the-cartridges liealongsidethe body of the screw and between the threads thereof.

An embodiment. of the inventioniis shown in the accompanying drawing,tin which Figures 1 and2 show a side and top view respectively of agunequippedwith the side magazine. I

Fig.= 3 shows'theinagazine itself'wlth the "inner screw shapedpartdrawnout ipartly.

F-igs. tand fi showa top and -end view respectively of details of thecartridge-feeding device.

.Figs. 6 and? show, schematically, two forms of construction employed in:feeding the cartridges forward "and for introducing the cartridges intothe barrelof thegun.

In the construction shown, the magazine is connected to an automatic:gun of a-known type; in which the-powder gases generated during firingare used tooperate a piston which-is connected to thebreech-block foropening the same closing of the breechblock a being carried outJoy-means of spring pressure.

Between these two cylinders 15. and

18 a spiral passageway is formed by the thread 17-, which correspondswith 1the diameter and the length of the cartridges. When the magazineis filled, the cartridges are arrangedwiththeir sides toward the in nercylinder 18 and they contact at the front, and rear, with the thread-17. By forming the magazine in this manner a greater number ofcartridges can be stored than in any magazine formerly known.

The cartridgesare driven toward the-gun barrel by means of the followingarrangement:

The wall of the innercylinder 18- is provided throughout its entirelength with a; spiral. slot; 19, .which is located intermediatethescrew-threads l7 and has the same fpitch as the screw threads. Inthis slot a slide-20- travels, whose foot 21 (see Eig. 6) slides inguides 22, 23, made of. steel. The guides are situated in the 'innercylinder 18- and consist of two arms .-22- and 28 the'first of which 22is slotted throughout its entire lengthiby asslot -24.- in which thetongue -25 -(seeFig. 3) of the slide 20 travels. Throughout the entirelength of the other arm .23-. aigroove extends for guidingthe ,foot 26-of the slide (see Fig.6). I

The arms +22, 23- are of the same length as themagazine and carry attheir front end a :cover -27.- for the front end of the magazine.The'front face of the cover is providedwith. a gear 28- with which asmaller gear 29 meshes. This gear 29- is-mounted on a fixed shaft 30whiclrextends into -aspring case 31 located on the side of the gun (seeFigs. 1 andw2). Thiscase contains a strong spiral spring (not shown)which may be wound up by means of an outer crank'handle -32.

Afterfther-spring (hereinafter calledthe -magazine springhhas Lbeenwound up by turning' t-he crank (and the gear 29) indirection of thearrows in Figs. 1 andq3 thearms 22and 23fwill berotated inthedirection-of the hands of a watch this causes the cartridges to; be'moved forward toward the gun barrel. Some stopping device for the gearwhich be managed from the outside of the gun may be employed if desired.Such a device is shown in Fig. 5 in which a pawl -32 is used to stop thegear :2%,). When the magazine is opened, that is during the firing, thecartridge series are fixed by the leading cartridge which strikesagainst the closed breech block or against a' knotin the lock case uponwhich the breech block is acting. I i In Fig. 6, I have shown one formof the device for feeding the cartridges forward to the lock case. Asthe car-tridgesreach the lock case, they travel upward on an inclinedguide -3l and are thereby lifted through an opening 35 (see Fig. 3) intothe lock case, where they are caught by the breech block and led intothe cartridge chamber in the usual manner.

In the construction shown in Fig. 7 the slide -20 is formedas'a headlying loose in the cartridge chamber. In this head a spr ng pressed flap-36 is arranged. WlVlllCll extends to some degree into the slot 19 ofthe inner magazine sleeve +18 and against which the arm 22- of theinterior guides act during the forward movement of the cartridges. Inthis con- 40 st'ruction, the high friction between the slide 20 and theguides 22, 28 is avoided and more force upon the cartridges is obtained.When the spiral spring in the casing 3l is wound up, the spring ressedfia 36 durin the ti iefn p p g g L H g "3, meansextendingthroughthefcore and of the spiral spring at each turn willtravel over the arms '22, 23. The slide head 20 in this incident ismoved rearwardly with the cartridges during the filling of the magazineand acts as aguide for the cartridges, preventing the same from.sticking fast or turning across the magazine. A slide of thisconstruction is preferred to the form shown in Figs. 3, 4 and 6. Afterthe magazine has been filled, the spiral spring is wound up by means ofthe crank handle -32. I

The reloading of the magazine may be accomplished in different, ways. Itmay be accomplished by introducing the cartridges through the magazineopening 37- (see Figs. 1 and 2) after the slide 20 has been led back to"its rear position. The magazine can bemade removable if desired guide isturned.

and may be replaced by another filled magazine.

The magazine can be adapted to different types of guns and adjusted fora greater or lesser number ofjcartridge by altering the diameter andlength of the cylinders.

If the spiral spring in the case 31- should not be capable of bringingforward the cartridges in a large magazine, an auxiliary spring may beplaced in the rear of the magaz ne to asslst 1n the operatlon. v

In the above specificatlon the magazine 1s described as'ofacylindricalform, but the form may of course be changed without departing from thespirit of the invention.
